To all whom t ,may concern.'

'Be 'it .known that "I, ,GEORGE P. MACIN rose, citizen of'jthe "UnitedStates, residing at WVakefield, .in thefcounty of Middlesex andv State of Massachusetts,"have invented.

new and useful Improvements yin Spoke-Engaging Antiskid Chain `Anchoring Means, of which the following is a specification.v

This invention relates to an anti-skid de- .'viice,'\vhich 'includes a chain adapted to eX- tend across `the tire of a vehicle wheel, and anchoring means attached to a spoke ofthe ,gvheel' and adapted to engage the termi-nal Ilinksof ,the chain in such manner aste coniinethelatter in its operative position. vThe vinvention is embodied lin the improved :in-- choring Vmeans hereinafter described and claimed, adapted to be conveniently and securely attached to a spoke and 'to coniinethe chain, yin such manner as to permit the convenientapplication and vremoval of the chain and fprevent its-automatic or accidental removal and loss. e

'The same reference characters indicate the same parts in all of the figures;

Referring 'first to Figures 1 2, 3, 4, and

(i, 12 represents a wheel felly, 13 a spoke thereof, A1st a tire on the felly; and 11:3 an

anti-skid chain anchored to the lspoke l?) and looped across the sides of the felly and the tread face ofthetire The-'terminal links ofthe chain arer engaged with guarded hooks, secured to the spoke by securing meansassociated with-'the hooks. yThe said securing .means in this embodiment of `the invention,

comprises `a pair of f duplicate clamping jaws 16 having opposed innerfaces 17 (Figure iformedto bear onopposite sides ofthevspoke '13, ears lat opposite-ends'of the 'faces 1`7 hav- 'ing bolt holes 19, and clampingbolts 2O engaged with saidearsand-adapted to confine the Yjaws on thespoke. Said-ears are desig' ynated Eby 18 in Figures and '3, by 18a in `Figure 4i, and by 18h in Figure/'6.

' -Each Jaw 1s Aprovided with afguarded hook composed of a curved neckportion 21, projecting'- from one side vofthe spoke, aterminal portio'11-,22, overhanging thefbase of the opposite directions from the plane ofthe `neck portion. Thehooks project yfrom opposite `Vsides-of the spoke. :Each 4iiuke hasy outer linkfguiding edge portionsQBa v(iFigs. 3 and 10) collectively forming a' substantially `semicircular edge and shoulder formthe neck portion 21 and is turned to slidev onto the neck, the link occupies its normal position relative to the major portion of the chain, and its removal fromthe hook is pre-vented by the edges '23". Each hook "neck port-ion, -and fiukes 23, lprojecting `in is adapted to be engaged with a terminal link of the chain 15 by a suitable manipulation ofthe linkthe latter being first turned to pass over the fliikes 23, and then given a quarter turn and transferred to the neck portion The flukes prevent the removal of the link from the hook, excepting by a rcversal of the above-described movements of the link, and as this reversal can not take place automatically, there is no liability of the loss of the chain.

rl`he jaws are formed as shown by Figures 2 andB, when the spoke is elliptical in cross section, and as shown by Figure 6, when the spoke is rectangular in cross section, the clamp being prevented from turning on the spoke by the form of the latter. Vhen the spoke is circular in cross section, as shown by Figure 4, I so form the jaws that portions thereof bear against the sides of the felly 12, as `shown by Figure 5, so that the felly prevents the jaws from turning on the spoke. To this end the neck portions 21 of the hooks are offset from the ears 18, and connected with the latter by arms 25, which bear on opposite sides of the felly.

The securingmeans may be composed of two independent units attached side by side to the spoke 13, as shown by Figure 7. Each unit is composed ofl a jaw 26, having boltengaging ears 27, and a jaw 28, having boltengaging ears 29. A guardedhook, constructed as above described, is formed on one of the ears of the jaw 26, the jaw 2S having no hook. The hook of one of the units projects from one side of the spoke, and ythe hook of the other unit projects from the opposite side, as shown by Figure 7 Each unit comprises a pair of clamping jaws having opposed inner faces formed to bear on opposite sides of a wheel spoke, bolt-engaging ears at opposite ends of said .inner faces, and a guarded hook projecting from one end ofone of the jaws and formed to be engaged with one of the terminal links of the chain in such manner as to prevent the loss of the chain. The other unit constitutes a suitable embodiment of means for engaging the other terminal link of the chain.

As shown by Figure 10, the securing means may be embodied in a jaw 30, having guarded hooks at its opposite ends, and an: opposed hookless jaw 31.

As shown by Figures 11 and 12, the securing means may be composed of two jaws 32, having arms 33, which bear on opposite sides of the felly, the guarded hooks being formed on said arms and offset therebyfrom the jaws. IVhen the hooks are offset from the jaws, and project from the sides ofthe felly, as shown by Figures l, 5, 11 and 12, they are in closer proximity to the tire than in the constructions shown by the other figures, so that shorter chains may be used.

I claim:

The combination with a spoked wheel, an i elastic tire and an anti-skid chain adapted to be looped across the sides of the wheel felly and the tread face of the tire; of a pair of guarded hooks, and means securing said hooks to a spoke of the wheel, the hooksprojecting from opposite sides of the i spoke, each hook including a. curved neck portion projecting from one side of the spokeand centrallyrthereof, a terminal portion overhanging the base` of the neck portion, and lukes on the terminal portion projecting in opposite directions from the plane of the neck portion, said flukes having inclined outer link-guiding edges formed to permit the passage of terminal chain linksy across the said terminal portions and onto the neck portions, when the links are held in abnormal positions, and shoulder-forming inner edges formed to preventthe removal of said links when they are in their normal positions, said neck portions supporting the looped chain in its operative position.

In testimony whereof Ihave aixed my signature.

GEORGE P. MACINTOSH.
